To (057, whom it may concern:

Be it known that I, ALEXANDER T. BROWN, of Syracuse, in the county of Onondagaand Stateof New York, have invented certain new and useful Improvements in Power-Transmitting Mechanism, of which the following is a specification.

My invention has for its object the prod uc-. tion of a power transmitting mechanism which is especially applicable for transmitting power from the motors of automobiles to I the propelling-wheels thereof, and is particutially, revoluble driven and driving members- A B, spur-gears G C C D D D means for preventing the rotation of the gears O O, and means for connecting the gear G to the driving member B. The driven member A is here shown as loosely mounted on a shaft 1), as provided with a hub a, and as consisting of a sprocket or gear wheel for driving the propelling-wheels of an automobile through;

the medium of a chain or other desirable means. Said driving member 13 is arranged with its axis substantially coincident with the axis of the driven member A, being here illustrated as fixed to the shaft 1) and as composed of the fly-wheel of the engine or othermotor for driving the automobile, to the pro pelling-wheels of which the member A is connected. The member B is usually formed with opposite hubs I) b and with an opening or chamber 19 which isgenerally partly inclosed by peripheral and side walls b The gears O O C are of unequal diameter and are preferably arranged with their axes substantially coincident with the axes of the driven and driving members A B. The gear 0, of intermediate size, is usually constantly revoluble with the driven member A, being here illustrated asffixed to the hub thereof, and the small and large gears C C are capable of rotation relatively to the driven member, being here shown as fixed, respectively, to disks C C ,.loosely revoluble around the axes of the members A B and having opposing sides formed with inwardly-extending flanges encircling annular surfaces of the driving member 13 and provided with peripheral engaging faces 0 c. In the illustrated embodiment of my invention the gear 0 partly encircles one of the hubs of the driving member and is provided with a hub 0 the gear 0 is loosely mounted on the other hub of the driving member B and the contiguous part of the shaft 1), and the gear O is loosely mounted on the hub c of the gear 0. Said gearsD D D are of unequal diameter, are fixed together, are preferably meshed with the gears C O 0 rotate as planetary gears around said gears G 0 C are generally supported by the driving member B eccentrically to its axis, and are revoluble with said driving member, being shown as arranged within the opening or chamber Z1 and as journaled on a spindle d, having its'ends supported by the side walls b 19 The gears D D D when constructed and arranged as shown and described connect the gear 0, revoluble with the driven member A. to the driving inemberB and to the gears 0 C capable of revolution relatively to the driven member, and transmit difierent rotary motions from the driving member 13 to the gear C, revoluble with the driven mem-' her A. I usually provide the driving member B with two sets of gears D D D arranged opposite to each other; but only one set may consists of brake-shoes 6 cf f, which respectively engage the faces 0 c and hold the disks C G stationary and are actuated by any suitable means unnecessary to describe herein. Said means for connecting the gear C to the driving member B is here shown as consisting of a transversely-split friction-ring g, interposed between contiguous annular surfaces of the driving member B and the disk C and having one end fixed-to the disk G a lever g, having its intermediate portion pivoted to the outer face of the disk 0 and one end thereof provided with an arm movable in a slot in the disk C and connected to the other end of the ring g, a spring g for holding the lever g in its inoperative position, and a collar g loosely mounted and longitudinally movable on the shaft 1) and having one end formed substantially conical and movable toward the disk C and engaged with the lever g for forcing the same into its operative position and having its other end provided with a groove for receiving a fork or other actuating means not necessary to illustrate.

In the operation of my power-transmitting mechanism when the brakeshoes e e are actuated to hold the disk C and the gear 0 stationary the driving member B and the gears O D D O rotate the driven member A forwardly at less speed than the driving member 13, and if said brake-shoes e e remain in their inoperative position and the brake-shoes ff are actuated to hold the disk C and the gear C stationary the driving member B and the gears C D D C rotate said member A backwardly' or in the reverse direction to that of the driving member l%. If it is desired to connect the gear C," to the driving member the brake-shoes 8 eff are allowed to remain inoperative and the collar g is moved lengthwise of the shaft 1) toward the disk C thus forcing the lever g into its operative position and locking the disk to the driving member B, whereupon the gears O C C D D D are locked together and rotate the member A forwardly with the same speed as the driving member B.

The construction and operation of my power-transmitting mechanism will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be obvious -to those skilled in the art that more or less change maybe made in the construction and arrangement of its parts without departing from the spirit of my invention.
